This is a list of United States Navy aircraft squadrons. Deactivated or disestablished squadrons are listed in the List of Inactive United States Navy aircraft squadrons. Navy aircraft squadrons are typically composed of several aircraft (from as few as two to as many as several dozen), the officers who fly them and the men and women that maintain them. Most squadrons also have a number of other administrative support personnel. Some of the activities listed are not technically "squadrons", but they all operate U.S. Navy aircraft in some capacity.
Squadrons and their history are listed in the Dictionary of American Naval Aviation Squadrons (DANAS).

While in the process of preparing a set of notes and illustrations about the F4U-4 configuration changes, I was somewhat surprised to find that the cannon-armed variant was designated both F4U-4B, the one I am familiar with, and F4U-4C, which didn't ring a bell right away other than C has been taken to mean a modification to add cannon armament, as in F4U-1C, SB2C -1C, and as it turns out, F8F-1C. My first thought was that the F4U-4C designation might be bogus until I discovered this photograph of BuNo 97448 in my files.

A modex is part of the Aircraft Visual Identification System* which consists of either one or two letters used by Dept of Navy (USN and USMC) aircraft to identify aircraft unit assignment and the aircraft side numbers (as assigned below).
The first letter of a modex indicates whether the organization (wing, group, squadron, station) owning the aircraft originated with Marine/Naval Air Forces Atlantic (A through M), Marine/Naval Air Forces Pacific (N through Z) or in the case of CNATRA a single letter (A through G) for the Training Wing.
In carrier air wings the first digit of a side number indicates an individual aircraft squadron in the air wing.
1xx and 2xx side numbers were assigned to fighter squadrons (VF) until the F-14 Tomcat was retired, they are now assigned to strike fighter squadrons (VFA) flying the F/A-18E or F/A-18F Super Hornet.
3xx and 4xx side numbers belonged to light attack aircraft squadrons (VA) flying the A-7 Corsair until the retirement of those aircraft when they were replaced by Strike Fighter Squadrons (VFA) flying the F/A-18C Hornet.
5xx side numbers were reserved for heavy attack aircraft squadrons (VA) flying the A-6 Intruder until the A-6 was retired. The 5xx side numbers are now assigned to the Electronic Attack (VAQ) Squadron (EA-6B/EA-18G).
6xx side numbers are assigned to the Airborne Early Warning(VAW) squadron (600-605) flying the E-2C, and the Helicopter Sea Combat (HSC) squadron (610 and up) flying the MH-60S helicopter.
7xx side numbers were assigned to the VS squadron flying the S-3 until the dissestablishment of those squadrons.
